CPU fan runs constantly

steveveg · 06-05-2008, 07:50 AM

Hi Ive just puchased a new pc, not sure if this is o.k. but the CPU fan runs constantly at 2700rpms it never stops and never drops below the rpms. CPU usage runs at steady 4-11%, its a new pc and ive hardly installed anything on it. Only asking this because my old PB's CPU fan used to run when i worked my pc hard and stop when system was idling. I've had a look in bios and theres no Q-fan option, i noticed Smart fan was Disabled so i enabled that and now its bought the CPU fan speed down to a steady 1700rpm but still runs constantly at that speed. I use PC Wizard 2008 to monitor my pc here are the specs,
Hardware Monitoring : ITE IT8718F
Voltage CPU: 1.22 V
+3.3V Voltage : 1.52 V
+5V Voltage : 5.07 V
+12V Voltage : 8.49 V
DIMM : 1.20 V
VTT : 1.52 V
VBAT : 3.22 V
Processor Fan : 1713 rpm
Chassis Fan : 2547 rpm
Power/Aux Fan : 10 rpm
Processor Temperature : 17 °C
Processor Temperature (Core 1) : 38 °C
Processor Temperature (Core 2) : 31 °C
Mainboard Temperature : 24 °C
Power/Aux Temperature : 23 °C
ACPI Thermal Zone : 40 °C
:
Video Monitoring : nVidia Driver
GPU Temperature : 62 °C
GPU Diode : 62.6 °C
GPU Fan : 100%
:
Hard Disk Monitoring : S.M.A.R.T
Hard Disk Temperature Hitachi HDT725025VLA380 : 32 °C

And here are my PC specs

CPU Intel® Core™ 2 Duo E4500 (2.2GHz)
Motherboard Foxconn 45CM/GM
Memory 1GB DDR2 PC2-4200 (2 x 512MB)
Hard Drive 250GB SATA hard drive
CD / DVD Drive Dual layer DVD±RW
Card Reader Flash Memory Card Drive (8 in 1)
Video / Graphics Card GeForce 7200GS PCI-E 128MB dedicated(up to 512MB hypermemory)
Sound Card Realtek ALC High Definition Audio
Network Card Realtek 8139 / 810X (Onboard)

Any advise would be great. Another thing i have noticed is my Processor frequency is 2200 Mhz but at current it states 1197 Mhz is that o.k. Please note i am no PC expert so be gentle.
Thanks Steve

Your +3.3 and +12 volt are really low, but that could be a software qlitch. Not for sure if it would even boot with 8.49 on the +12V. If your CPU runs steady at 4 to 11% theres got to be something running in the back ground. Have you checked under processes to see whats eating your CPU time?

Cheers IamOne

Ive looked and theres 51 processes and my cp usage is hovering around 3-8%in the CPU colomn its highest ones are
system idle 95
taskmgr.exe 5
dwm.exe 5
system 0 -1

in the memory column the highest ones are
svchost.exe 43000k
mcshield 30000k
iexplorer.exe 29000k
dwm.exe 25000k
msiexec.exe 11000k

the above memory reading are a rough guide and the do fluctulate constantly around those reading.

Thanks,
Steve

Oh Vista, well Vista eats up more. the dwm.exe is the Aero/Live window previews. CPU temps. are alittle on the warm side, but I beat your running a stock cooler. If your CPU is running around the mid 30c idle the 1700rpm for a stock cooler is not to uncommon

Steveveg,

It should be your PSU. Please check it on another PC (if you have any free). What's your PSU?

Oh and you shouldn't be worried about your FAN. Download Speed Fan program and take a look if you can control CPU Fan's RPM.

If not, go then to your BIOS adjust it. I suggest leaving ~1800 rpm and monitoring temperatoru of your cPU.

Thats it for now.. waiting for reply
